Deathspell Omega is a French black metal band formed in 1998 in Poitiers. The group is an anonymous collective that has never confirmed the identity of any of its members.
Their lyrical content often deals with metaphysical Satanism, and the philosophies of Bataille and Hegel.
From 2004 to 2010, the band released a trilogy of concept albums - Si monvmentvm reqvires, circvmspice, Fas - Ite, Maledicti, in Ignem Aeternum and Paracletus - which focus on the theological aspects of God and Satan. With the band's seventh album The Furnaces of Palingenesia, there was a shift in lyrical focus to anti-authoritarian political themes.
The band's eighth and most recent album, The Long Defeat, was released on 23 March 2022. The band described the album as " the first emanation of the third era of Deathspell Omega".
